Bought a aliexpress kit
(i hope post is is not mainline audio so general tab suits for it )
I must say best 6$ ever spent

comes with all including screws and wires pre tinned and stripped
coils pretinned wao!


there is a SMD chip that all mediocre diy guys can solder with sharp tip IC CD9088

all others parts are in the legend print value and position ..


its cute tiny , v v sensistive

first go
> no sound no light
i check forgt to solder 1 point
second go
hiss ..AM working FM is just noise not regular his
> did a little twist to trimmer caps
wah FM is there

but speaker rattling plastic sound

BUG : cut pc metals struck to diaphragm ..removed all waah
so super sound ..

catches all fm with antenna close ..no drift in touching ;)

MAIN feature
AMAzingly it gves no hiss in fm tune it ...just music or noting
